 == What Verilator Does

 Verilator has typically similar or better performance versus the commercial
 Verilog simulators (Carbon Design Systems Carbonator, Modelsim, Cadence
 Incisive/NC-Verilog, Synopsys VCS, VTOC, and Pragmatic CVer/CVC). But,
-Verilator is free, so you can spend on computes rather than licenses. Thus
-Verilator gives you more cycles/dollar than anything else available.
